Description
TECHNICAL FIELD
[0001] The present disclosure relates to communications and, in
particular, to a data processing method based on a radio access
technology, and a transmission node.
BACKGROUND
[0002] In wireless communication systems, different users use
multiple access technologies to share wireless communication
resources. Common multiple access technologies include Frequency
Division Multiplexing Access (FDMA), Time Division Multiplexing
Access (TDMA), Code Division Multiplexing Access (CDMA), Orthogonal
Frequency Division Multiplexing Access (OFDMA) and Single
Carrier-Orthogonal Frequency Division Multiplexing Access
(SC-OFDMA).
[0003] For Long Term Evolution (LTE) system in Release 12, the
SC-OFDMA technology and the OFDMA technology are used in uplink and
downlink respectively. In LTE Release 13, the Narrow Band-Internet
of Things (NB-IOT) technology starts to be studied. The NB-IOT
uplink transmission involves two multiple access technologies: the
FMDA technology based on Gaussian Filtered Minimum Shift Keying
(GMSK) modulation, and the SC-OFDMA technology. The FDMA technology
based on GMSK modulation is featured by a low Peak to Average Power
Ratio (PAPR), helping improve power amplification efficiency and
thereby limiting terminal costs and ensuring coverage. The FDMA
technology based on GMSK modulation has the advantage of being
insensitive to timing precision but has the disadvantage of
relatively low spectral efficiency. SC-OFDMA has the advantage of
high spectral efficiency but, in general, has a larger PAPR than
the FMDA technology based on GMSK modulation and requires a higher
timing precision. The PAPR of LTE SC-OFDMA can be reduced by some
modulation technologies or time-frequency domain precoding
technologies. The FMDA technology based on GMSK modulation and the
SC-OFDMA technology have their respective applications due to their
respective advantages and disadvantages. For example, in deep
coverage, uplink synchronization is inaccurate and high
transmission power also requires low PAPR for a terminal, so FMDA
is more applicable. In ordinary coverage, SC-OFDMA is a better
choice to ensure spectral efficiency.
[0004] Uplink NB-IOT may use both the FMDA technology based on GMSK
modulation and the SC-OFDMA technology. In addition, in future 5G
wireless communication systems, one radio access technology (RAT)
cannot meet diversified requirements and one system may use
multiple RATs, for example, the orthogonal multiple access
technology and the non-orthogonal multiple access technology,
simultaneously.
[0005] No efficient solution has been provided to solve the problem
in merging different radio access technologies in the related
art.

[0200] The present disclosure will be detailed below in conjunction
with preferred embodiments and implementations.
[0201] In all preferred embodiments described below, it is assumed
that the first transmission node is a base station and the second
transmission node is a terminal. Of course, alternatively, the
first transmission node may be a terminal and the second
transmission node may be a base station.
Preferred Embodiment 1 Includes Three Implementations
[0202] Implementation 1.1:
[0203] This implementation assumes an uplink LTE-IOT transmission.
FIG. 5 is a first schematic diagram of a timing relationship of a
base station according to a preferred embodiment of the present
disclosure. As shown in FIG. 5, a number of time domain resources
are arranged in sequence of a first resource unit ReEl 1, a third
resource unit ReEl 3, a second resource unit ReEl 2, a fourth
resource unit ReEl 4 and a first resource unit ReEl 1 as time
increases. The base station receives and processes data on ReEl 1
and ReEl 2 by using the FDMA mode and the SC-OFDMA mode
respectively. ReEl 3 and ReEl 4 are guard intervals. A time length
of ReEl 3 and a time length of ReEl 4 are T3 and T4 respectively.
The guard intervals are mainly designed for a switching delay when
the base station switches between different multiple access modes
and for a timing requirement of an uplink transmission. T3 is
larger than T4 in this implementation because switching delay and
timing are both taken into account for T3 whereas only switching
delay is taken into account for T4. Unequal guard intervals may
allow more time domain resources to be reserved for a certain
resource unit considering that different multiple access modes may
have different transmission rates; or different guard intervals may
be designed to meet different transmission timing precision
requirements; or different guard intervals are required when
applied to different coverage areas. To simplify the design of
lengths of the guard intervals, it is feasible to specify that the
time length of ReEl 3 and the time length of ReEl 4 are
proportional to those of ReEl 2 and ReEl 1 respectively or it is
feasible to specify that the time length of ReEl 3 and the time
length of ReEl 4 are proportional to those of ReEl 1 and ReEl 2
respectively. In this implementation, FDMA has a lower spectral
efficiency and requires a lower timing precision. Therefore, a
smaller guard interval is designed and more time domain resources
are allocated for data transmission.
[0204] Implementation 1.2:
[0205] This implementation assumes a number of time domain
resources. FIG. 6 is a second schematic diagram of a timing
relationship of a base station according to a preferred embodiment
of the present disclosure. As shown in FIG. 6, a number of time
domain resources are arranged in sequence of a first resource unit
ReEl 1, a third resource unit ReEl 3, a second resource unit ReEl
2, a fourth resource unit ReEl 4 and a first resource unit ReEl 1
as time increases. The base station receives and processes data on
ReEl 1 and ReEl 2 by using the time domain code division mode and
the SC-OFDMA mode respectively. ReEl 3 and ReEl 4 are guard
intervals. A time length of ReEl 3 and a time length of ReEl 4 are
T3 and T4 respectively. The guard intervals are mainly designed for
a switching delay between different multiple access modes and for a
timing requirement. T3 is equal to T4 in this implementation.
Switching delay from ReEl 1 to ReEl 2 and timing are taken into
account for T3. Switching delay from ReEl 2 to ReEl 1 and timing
are taken into account for T4. In this implementation, equal guard
intervals are designed and equal time domain resources are reserved
for two multiple access modes. To simplify the design of lengths of
the guard intervals, it is feasible to specify that the time length
of ReEl 3 and the time length of ReEl 4 are proportional to those
of ReEl 2 and ReEl 1 respectively or it is feasible to specify that
the time length of ReEl 3 and the time length of ReEl 4 are
proportional to those of ReEl 1 and ReEl 2 respectively.
[0206] Implementation 1.3:
[0207] This implementation assumes an uplink LTE-IOT transmission.
FIG. 7 is a third schematic diagram of a timing relationship of a
base station according to a preferred embodiment of the present
disclosure. As shown in FIG. 7, a number of time domain resources
are arranged in sequence of a first resource unit ReEl 1, a third
resource unit ReEl 3, a second resource unit ReEl 2 and a first
resource unit ReEl 1 as time increases. The base station receives
and processes data on ReEl 1 and ReEl 2 by using the FDMA mode and
the SC-OFDMA mode respectively. ReEl 3 is a guard interval. A time
length of ReEl 3 is T3. In this implementation, T4 is equal to 0
and T3 is not equal to T4. The guard interval is mainly designed
for a switching delay between different multiple access modes and
for a timing requirement. Unequal guard intervals may allow more
time domain resources to be reserved for a certain resource unit
considering that different multiple access modes may have different
transmission rates; or different guard intervals may be designed to
meet different transmission timing precision requirements; or
different guard intervals are required when applied to different
coverage areas. In this implementation, FDMA does not require a
high timing precision, so it is not needed to design a guard
interval in consideration for timing and it is feasible to obtain a
switching interval by adjusting the time at which ReEl 2 receives
data.
[0208] Implementation 1.4:
[0209] This implementation assumes an uplink LTE-IOT transmission.
FIG. 8 is a fourth schematic diagram of a timing relationship of a
base station according to a preferred embodiment of the present
disclosure. As shown in FIG. 8, a number of time domain resources
are arranged in sequence of a first resource unit ReEl 1, a third
resource unit ReEl 3 and a second resource unit ReEl 2 as time
increases. The base station receives and processes data on ReEl 1
and ReEl 2 by using the SC-OFDMA mode and the FDMA mode
respectively. A time length of ReEl 3 depends on two factors. One
is T1, which is a sum of a switching delay when the base station
switches between different multiple access modes and a maximum
timing advance. The other is T2, which is an uplink timing error.
In this implementation, uplink synchronization of a terminal is not
performed or uplink synchronization is not accurate, so a guard
interval is reserved. Of course, the base station may receive data
after the switching delay T1. The time length of ReEl 3 may be an
integral multiple of a specified time unit. T1 may be in a fixed
proportion to T2.
Preferred Embodiment 2 Includes Five Implementations

arranged in sequence of a first resource unit ReEl 1, a third
resource unit ReEl 3, a second resource unit ReEl 2 and a first
resource unit ReEl 1 as time increases. The base station receives
and processes data on ReEl 1 and ReEl 2 by using different multiple
access modes or different modulation modes. T23, which is a sum of
time lengths of ReEl 2 and ReEl 3, and T1, which is a time length
of ReEl 1, satisfy: T1=T23=T0, where T0 is a time length unit. The
time length unit in this implementation is N subframes, where the
number of subframes of one radio frame can be exactly divided by N.
This design is conducive to the compatibility of two RATs, makes
the frame structure simpler and clearer, and simplifies the timing
relationship, including HARQ and retransmission timing.
[0216] Implementation 2.4:
[0217] In this implementation, FIG. 12 is an eighth schematic
diagram of a timing relationship of a base station according to a

arranged in sequence of a first resource unit ReEl 1, a third
resource unit ReEl 3, a second resource unit ReEl 2, a fourth
resource unit ReEl 4 and a first resource unit ReEl 1 as time
increases. The base station receives and processes data on ReEl 1
and ReEl 2 by using different multiple access modes or different
modulation modes. T1, which is a time length of ReEl 1, and T234,
which is a sum of time lengths of ReEl 2, ReEl 3 and ReEl 4,
satisfy: T1=T234=T0, where T0 is a time length unit. The time
length unit in this implementation is N subframes, where the number
of subframes of one radio frame can be exactly divided by N. This
design is conducive to the compatibility of two RATs, makes the

resource unit ReEl 2 as time increases. The base station receives
and processes data on ReEl 1 and ReEl 2 by using different multiple
access modes or different modulation modes. T123, which is a sum of
time lengths of ReEl 1, ReEl 2 and ReEl 3 satisfies: T123=T0, where
T0 is a time length unit. The time length unit in this
implementation is N subframes, where the number of subframes of one
radio frame can be exactly divided by N. This design is conducive

and clearer, and simplifies the timing relationship, including HARQ
and retransmission timing.
Preferred Embodiment 3 Includes Three Implementations
[0220] Implementation 3.1:
[0221] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the FDMA mode and the SC-OFDMA mode
respectively. The FDMA uses GMSK modulation. The SC-OFDMA uses QAM
modulation. Terminals are divided into low-coverage UEs,
medium-coverage UEs and high-coverage UEs as the distances between
the terminals and a base station increase. Medium-coverage and
low-coverage UEs perform uplink transmission on a first resource
unit by using SC-OFDMA. High-coverage UEs perform uplink
transmission on a second resource unit by using FDMA. High-coverage
UEs require higher transmit power. The FDMA mode based on GMSK
modulation has a relatively low PAPR, ensuring coverage of low-cost
UEs. Additionally, the FDMA mode does not require a high timing
precision, reducing synchronization overheads and improving system
capacity. Medium-coverage and low-coverage UEs use SC-OFDMA, so the
spectral efficiency can be improved. The base station receives data
on the first resource unit and the second resource unit separately.
After determining coverage areas of UEs, the base station processes
data by using the FDMA mode and the SC-OFDMA mode separately.
[0222] Implementation 3.2:
[0223] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. This implementation assumes
that when a frequency domain bandwidth is smaller than a predefined
F0, a terminal performs an uplink transmission on a first resource
unit by using the SC-OFDMA mode; otherwise, the terminal performs
an uplink transmission on a second resource unit by using the FDMA
mode based on GMSK modulation. Assuming that there are two
spectrums: a spectrum A having a frequency length F1 and a spectrum
B having a frequency length F2, F1<F0<F2, the SC-OFDMA mode
and the FDMA mode based on GMSK modulation are used on the spectrum
A and the spectrum B respectively. The spectrum A has a smaller
length and SC-OFDMA mode has a higher spectral efficiency, so this
spectrum can be used to achieve higher-rate data transmission. A
base station receives data on the first resource unit and the
second resource unit separately and processes data by using the
SC-OFDMA mode and the FDMA mode separately.
[0224] Implementation 3.3:
[0225] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. In this implementation, a
base station configures a terminal to use the first RAT to send
data on a first resource unit and use the second RAT to send data
on a second resource unit. The base station receives data from the
terminal on the first resource unit and processes the data by using
the first RAT.
Preferred Embodiment 4
[0226] This embodiment assumes an uplink NB-IOT transmission. A
first RAT and a second RAT both use the SC-OFDMA mode. A
sub-carrier spacing of the first RAT and a sub-carrier spacing of
the second RAT are 3.75 kHz and 15 kHz respectively. In this
embodiment, a base station configures a terminal to use the first
RAT to send data on a first resource unit. In frequency domain,
subcarriers of the first resource unit corresponding to the first
RAT are located in the center of a frequency band, and subcarriers
of a second resource unit corresponding to the second RAT are
distributed on both sides of the subcarriers of the first RAT and
located at both sides of the frequency band. The base station
receives data from the terminal on the first resource unit and
processes the data by using the first RAT. Frequency domain
resources of one RAT are located at both sides of frequency domain
resources of another RAT, helping flexibly changing the sizes of
frequency domain resources and maintaining features of a
single-carrier OFDMA and thereby reducing a PAPR.
Preferred Embodiment 5
[0227] This embodiment assumes an uplink NB-IOT transmission. A
first RAT and a second RAT both use the SC-OFDMA mode. A
sub-carrier spacing of the first RAT and a sub-carrier spacing of
the second RAT are 3.75 kHz and 15 kHz respectively. In this
embodiment, FIG. 14 is a tenth schematic diagram of a timing
relationship of a base station according to a preferred embodiment
of the present disclosure. As shown in FIG. 14, the base station
configures a terminal to use the first RAT to send data on a first
resource unit. In frequency domain, subcarriers of the first
resource unit corresponding to the first RAT are located in the
center of a frequency band, and subcarriers of a second resource
unit corresponding to the second RAT are distributed on both sides
of the subcarriers of the first RAT and located at both sides of
the frequency band. In time domain, a ratio of a length of the
first resource unit corresponding to the first RAT to a length of
the second resource unit corresponding to the second RAT is 4:1.
The base station receives data from the terminal on the first
resource unit and processes the data by using the first RAT. This
design in time domain is conducive to the compatibility of two
RATs, makes the frame structure simpler and clearer, and simplifies
the timing relationship, including HARQ and retransmission
timing.
Preferred Embodiment 6 Includes Five Implementations
[0228] Implementation 6.1:
[0229] This implementation assumes an uplink LTE-IOT transmission.
FIG. 15 is an eleventh schematic diagram of a timing relationship
of a base station according to a preferred embodiment of the
present disclosure. As shown in FIG. 15, a number of time domain
resources are arranged in sequence of a first resource unit ReEl 1,
a third resource unit ReEl 3, a second resource unit ReEl 2, a
fourth resource unit ReEl 4 and a first resource unit ReEl 1 as
time increases. A terminal sends data on ReEl 1 and ReEl 2 by using
the FDMA mode and the SC-OFDMA mode respectively. ReEl 3 and ReEl 4
are guard intervals. A time length of ReEl 3 and a time length of
ReEl 4 are T3 and T4 respectively. The guard intervals are mainly
designed for a switching delay when the base station switches
between different multiple access modes and designed for a timing
requirement of uplink transmission. T3 is larger than T4 in this
implementation because switching delay and timing are both taken
into account for T3 whereas only switching delay is taken into
account for T4.
[0230] Unequal guard intervals may allow more time domain resources
to be reserved for a certain resource unit considering that
different multiple access modes may have different transmission
rates; or different guard intervals may be designed to meet
different transmission timing precision requirements; or different
guard intervals are required when applied to different coverage
areas. To simplify the design of lengths of the guard intervals, it
is feasible to specify that the time length of ReEl 3 and the time
length of ReEl 4 are proportional to those of ReEl 2 and ReEl 1
respectively or it is feasible to specify that the time length of
ReEl 3 and the time length of ReEl 4 are proportional to those of
ReEl 1 and ReEl 2 respectively. In this implementation, FDMA has a
lower spectral efficiency and requires a lower timing precision.
Therefore, a smaller guard interval is designed and more time
domain resources are allocated for data transmission.
[0231] Implementation 6.2:
[0232] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. In this implementation, an
RRC connection of a terminal has not been established. The terminal
detects a system message sent by a base station. The terminal
decides to use the first RAT or the second RAT according to the
system message, or a terminal that cannot support two RATs
simultaneously determines, according to the system message, whether
to use a RAT supported by the terminal to send data. The terminal
processes data after selecting a RAT, and sends data on a
corresponding first or second resource unit.
[0233] Implementation 6.3:
[0234] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. In this implementation, an
RRC connection of a terminal has not been established. The terminal
performs a channel measurement, such as a Reference Signal Received
Power (RSRP) measurement, to determine a channel condition. The
terminal determines a level of repeat times according to a
measurement result, selects a RAT and then processes data. In this
implementation, after the measurement, the terminal finds that the
channel condition is poor, so the terminal selects the first RAT
and sends data on a corresponding first resource unit. The first
RAT has a higher spectral efficiency than the second RAT. When the
first RAT is used in a low signal-noise ratio, more data is
transmitted or the transmission bit rate is reduced, thereby
ensuring data transmission of the terminal.
[0235] Implementation 6.4:
[0236] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. In this implementation, an
RRC connection of a terminal has not been established. The terminal
performs a channel measurement, such as a Reference Signal Received
Power (RSRP) measurement, to determine a channel condition. The
terminal selects a RAT according to a measurement result and then
processes data. In this implementation, after the measurement, the
terminal finds that the channel condition is poor and accordingly
determines that the terminal is in a deep-coverage area. Thus, the
terminal selects the second RAT and sends data on a corresponding
second resource unit. UEs in deep coverage require a higher
transmit power. The FDMA mode based on GMSK modulation has a
relatively low PAPR, ensuring coverage of low-cost UEs.
Additionally, the FDMA mode does not require a high timing
precision, reducing synchronization overheads and improving system
capacity.
[0237] Implementation 6.5:
[0238] This implementation assumes an uplink NB-IOT transmission. A
first RAT and a second RAT use the SC-OFDMA mode and the FDMA mode
based on GMSK modulation respectively. In this implementation, an
RRC connection of a terminal has been established. The terminal
detects a configuration message sent by a base station. The
terminal decides to use the first RAT or the second RAT according
to the configuration message, or a terminal that cannot support two
RATs simultaneously determines, according to the configuration
message, whether to use a RAT supported by the terminal to send
data. The configuration information may be information about a
level of transmission repeat times. The terminal processes data
after selecting a RAT, and sends data on a corresponding first or
second resource unit.
Preferred Embodiment 7
[0239] In this embodiment, according to different supported RAT
types, that is, according to different terminal capabilities,
terminals are divided into two types: a first type of terminals
that support an SC-OFDMA mode having a sub-carrier spacing of 3.75
kHz and using a single carrier for data transmission, and a second
type of terminals that support an SC-OFDMA mode having a
sub-carrier spacing of 15 kHz and using a single carrier and
multiple carriers for data transmission. Alternatively, terminals
are divided into two types: a first type of terminals that support
an SC-OFDMA mode using a single carrier for data transmission and
having sub-carrier spacings of 3.75 kHz and 15 kHz, and a second
type of terminals that support an SC-OFDMA mode using multiple
carriers for data transmission and having a sub-carrier spacing of
15 kHz. Alternatively, terminals are divided into three types: a
first type of terminals that support an SC-OFDMA mode using a
single carrier for data transmission and having a sub-carrier
spacing of 3.75 kHz, a second type of terminals that support an
SC-OFDMA mode using a single carrier for data transmission and
having a sub-carrier spacing of 15 kHz, and a third type of
terminals that support an SC-OFDMA mode using multiple carriers for
data transmission and having a sub-carrier spacing of 15 kHz.
Preferred Embodiment 8
[0240] In this embodiment, a base station allocates different
resource units, namely, physical random access channel (PRACH)
resources 1/2/3, which correspond to terminal capabilities 1/2/3
respectively. That is, terminals with terminal capabilities of
1/2/3 access a network by using PRACH resources 1/2/3 respectively.
For details about division of terminal capabilities 1/2/3, see
embodiment 7. The base station receives, on the PRACH resource 1,
data sent by a terminal, and uses a RAT corresponding to the
terminal capability 1 to demodulate and decode data. After
determining the terminal capability 1 and its corresponding RAT,
the base station schedules resources, allocates a corresponding
resource to the terminal, and sends configuration information to
the terminal on a corresponding resource unit, where the
configuration information is used for data processing and resource
selection for uplink transmission of the terminal.
Preferred Embodiment 9
[0241] In this embodiment, a base station allocates different

respectively. That is, terminals with terminal capabilities of
1/2/3 access a network by using PRACH resources 1/2/3 respectively.
For details about division of terminal capabilities 1/2/3, see
embodiment 7. In this embodiment, a terminal with a terminal
capability of 1 accesses the network on a PRACH 1. A terminal sends

capability. The terminal also receives, on a corresponding resource
unit, configuration information sent by the base station, and
performs an uplink data processing and selects a resource location
according to the configuration information.
